Ok, I see what you mean now... But I'm not quite so sure how awkward that would be to have a combined "set active set" menu and "edit any set" thing all trying to be packaged together like that.

I'll see if I can do something for this with the current system. This is another thing that would maybe be a bit awkward on an inline editor in the popup menu, I guess you would be talking then about switching things on screen just when keyboard focus went into each field?

This is not normally done in filleting because trying to suddenly stop a regular fillet opens up a hole when there is an abrupt change from a curved fillet piece back to the regular portion of the object.

If you want to use variable radius to handle that hole issue by having the radius shrink to zero at that spot, then you could potentially try that by cutting the edge into multiple edges using the Edit > Trim command with the "Add trim points" option. Add a trim point at your "stop point" so it's split into different edges there. This does not seem to work very well though, it's not really something that the fillet engine is expecting to deal with.

Sorry, no probably not. If you don't want a set of points you've already defined you would just need to cancel out the fillet and start a new one.

> Would id be a good idea to have some kind of visual indicator of the fillet points created?

Yeah I'll see if I can put up the current set of points on screen.

> I have know idea what amount work it would involve, but if it's an easy thing, having adjustable on-screen handles would be very cool.

Unfortunately that involves a whole lot of work and much more fundamental changes to how regular filleting would work. I'd like to have something like that in the future at some point but it's not what I'm trying to get done right now.

You can put any number of points, the points go on the original edges. But usually you'll want to be fairly sparing with the number of points used because using too many too tightly packed together will make for a sort of "bunching" effect:

A man journey's out of the village for a few days and a luau is thrown without him!
What a great surprise.

You are awesome, Michael!!!
Oh, I so can't wait to play with variable fillets.

So, question:

1) since points can't be deleted (if we flub), so I'm guessing you can re-position them?
2) will it work on fillets that branch off from intersections? What I mean is, will this work on all the complicated places fillets usually work?
3) The question asked earlier... but can you assign any type of rounding; G1-3 separately on each control set?
4) Okay, and one I thought about a long time ago... can the variability be as simply as filleting just one edge corner, where you can start at one radius and end at another.. looking kinda conical?

> 1) since points can't be deleted (if we flub), so I'm guessing you can re-position them?

Nope, if you have put them in the wrong place then you'd just need to cancel the command and start a new one. Same thing as if you selected the wrong edges to fillet.

Well, it tries to do it in the same places, but it seems that they're a bit more finicky when it comes to intersections though.

> 3) The question asked earlier... but can you assign any type of rounding; G1-3 separately on each control set?

No, currently the setting for whether doing round or G1-3 applies to all the fillets being done, there isn't currently any way to assign different rounding styles to different fillet sets. Maybe in the future I can add something in for multiple "edge sets" as well as "point sets" that might be a better fit for also assigning these per-edge properties.

You can do the "just one edge" thing, but it currently does an "ease-in/ease-out" type blending on it so it doesn't look quite conical, it looks like this:

I'm trying to see about maybe fitting in a "linear" option you could enable somewhere to get a conical shape, or also maybe if you're doing an edge with only 2 stations along it I should just do a linear blend in that case, I haven't quite figured that out yet.

Hi wim, you didn't do anything wrong, it's just a bug in filleting where it's having a problem in the step where it tries to trim away the area of the main object to make a place to attach the fillet. When that happens the fillet surface will still be generated so you have something to work with and you can use Edit > Separate on your main object to break it into individual surfaces and then use Edit > Trim on each surrounding surface to cut it with the edge of the fillet to finish the model.
